~ Perennials That Bloom in Summer ~ Red Valerian

Perennial flowers are more or less like shrubs and bushes in their growth habit. Like shrubs, they offer permanent greenery in the garden for several years; only thing is that along with foliage, you get to enjoy lovely blooms. The advantage of planting perennials is they don't need to be uprooted even after the blooming period is over, which is the case with seasonal and annual flowers. Thus, many hobbyists prefer including them in their gardens.

In case you don't have enough time for gardening and nurturing plants, perennial flowers are the ideal choice. Perennials are often selected for large gardens. Based on the variety you have planted, they will bloom for a specific season every year. Hence, if you consider the mode of flowering, they resemble annuals. With so much variation in size, color, shape, and pattern, you can find many blooming perennial flowers well-suited for your landscape design.

The Red valerian (Centranthus ruber) is very famous for its ornamental flowers. It blooms for a longer duration in cooler climatic conditions. It is a widely grown ornamental subshrub, best adapted in USDA zones 3 - 9. You can plant stem cuttings of valerian in dry soil. Flower buds start developing in early spring and continue to bloom throughout summer. Irrespective of the individual flowers being as tiny as 2 cm, the inflorescence is huge and looks spectacular. You will usually see purplish-red flowers, with occasional blooms of white and lavender. The plant is also called Jupiter's beard and spur valerian.
